Python Sdk websocket not working

[Thiyaneswaran]

Hi Team,
I am using python sdk WebSocket streaming code to get live ticks but we are not getting ticks. Sharing the sample code let us know is there any mistake from our side if not check from your end. With the same code login is working fine and in streaming is not working properly.

# package import statement
from smartapi import SmartConnect
from smartapi import SmartWebSocket
 #or from smartapi.smartConnect import SmartConnect
import pyotp
#import smartapi.smartExceptions(for smartExceptions)

#create object of call
obj=SmartConnect(api_key="r8psjpm9")
                #optional
                #access_token = "your access token",
                #refresh_token = "your refresh_token")

#login api call

data = obj.generateSession("T41918","****",pyotp.TOTP("****").now())
print(data)
refreshToken= data['data']['refreshToken']

#fetch the feedtoken
feedToken=obj.getfeedToken()

#fetch User Profile
userProfile= obj.getProfile(refreshToken)
print(userProfile)
#place order


# feed_token=092017047
print(feedToken)
FEED_TOKEN=feedToken
CLIENT_CODE="T41918"
# token="mcx_fo|224395"
token="nse_fo|41665"    #SAMPLE: nse_cm|2885&nse_cm|1594&nse_cm|11536&nse_cm|3045
# token="mcx_fo|226745&mcx_fo|220822&mcx_fo|227182&mcx_fo|221599"
task="mw"   # mw|sfi|dp

ss = SmartWebSocket(FEED_TOKEN, CLIENT_CODE)

def on_message(ws, message):
    print("Ticks: {}".format(message))
    
def on_open(ws):
    print("on open")
    ss.subscribe(task,token)
    
def on_error(ws, error):
    print(error)
    
def on_close(ws):
    print("Close")

# Assign the callbacks.
ss._on_open = on_open
ss._on_message = on_message
ss._on_error = on_error
ss._on_close = on_close

ss.connect()
